exact description, reference being had to the orcin bars us adding strength and accompanying drawings, forming a part g' y t0 the entire Ighereof. In 1g. 5 I ave shown the vertical webs My invention relates to a railway crossing of the 035.1110 alls as helhg formed Wlder wherein the intersecting crossing rails are OWard hhell' OWeI' ends, thus ohmlhg a cast solid with one another, and which cross p p g 1n the all, which ing rails are in boX form, or in an inverted letter U.

further object of my invention is to struction is applicable tion requiring an extra heavy rai In Fig. 6 I have shown a frog constructed for railway construcl with my invention and wherein the crossing rails are of inverted U-shape.
